Programmable Interrupt Controller - an overview ScienceDirect …

In computing, a programmable interrupt controller (PIC) is an integrated circuit that helps a microprocessor (or CPU) handle interrupt requests (IRQ) coming from multiple different sources (like external I/O devices) which may occur simultaneously. It helps prioritize IRQs so that the CPU switches execution to the most appropriate interrupt handler (ISR) after the PIC assesses the IRQ's relative priorities. Common modes of interrupt priority include hard priorities, rotating prior… WebSoftware Generated Interrupt (SGI) This is generated explicitly by software by writing to a dedicated distributor register, the Software Generated Interrupt Register (ICDSGIR). It is most commonly used for inter-core communication. SGIs can be targeted at all, or a selected group of cores in the system.

WebThe IRQ Controller API allows interrupt dependend applications to be easily portable across a wide range of controllers. Note The default implementation for Arm GIC (Generic Interrupt Controller) can be found in irq_ctrl_gic.c. It uses weak functions thus it can easily be overwritten by an alternative user implementation if needed. WebThe Intel 8259 is a Programmable Interrupt Controller (PIC) designed for the Intel 8085 and Intel 8086 microprocessors. The initial part was 8259, a later A suffix version was upward compatible and usable with the 8086 or 8088 processor.
